Super Mario Flash 2 Aced

SMF2 Aced is a hack made by BrokenAce, and is sarcastically claimed to be one of the best hacks in existence, only second to Crash Bandicoot Edition. It mixes clashing sprites like Pokemans, demon Marios and lots of tiles from pre-rendered 3D Mario games (particularly the NSMB series, not so much DKC).
